USDA SOIL TEXTURING KITS (Eight calibrated samples)
Now soil scientists, geologists, and engineers can practice and
calibrate the accuracy of their soil texturing skills! The USDA Soil
Texture kits consist of eight air-dried soil samples which has been
passed through a 1/4-inch wire screen and placed in plastic zip-lock
bags.
Texture ranges from loamy sand to silt loam to clay. Each kit
includes a listing of the Texture Class name contained within the kit,
as well as sand, silt, and clay. The soil specimens are collected
from the Red River Valley near Fargo, North Dakota; near Detroit
Lakes, Minnesota; in the Missouri River bottom near Onawa, Iowa, and
near Ames, Iowa.
